摩擦摆支座的简化模拟方法
A simplified simulation method of friction pendulum bearings
摘要
Abstract
In order to improve the computation efficiency and simulation accuracy, a novel simplified simulation method for friction pendulum bearing ( FPB) is proposed. The behavior of FPB was analyzed based on the stress characteristics of the slider of FPB. Then, a novel simplified FPB model with a single pendulum and a nonlinear spring was established. The mechanical behavior of the simplified model was analyzed and it conformed well to the basic requirements of FPB. Furthermore, shaking table tests of a concrete slab block structure isolated by four FPBs were carried out, followed by finite element simulations of the test using the proposed simplified model. Three waves and eleven loading scenarios were selected in the test. The results show that the overall trend of the relative displacement time-history curves, the horizontal acceleration time-history curves and the vertical acceleration time-history curves from the numerical simulation match in a good manner with those obtained from the tests. Specifically, it is found that the difference of the peak value within these curves between the simulation and test results is less than 15％, which means that the proposed simplified model can be used to simulate the FPB behaviors under dynamic loadings with acceptable accuracy for engineering purposes.关键词
